THE EFFECT OF BEECH WOOD DRYING ON HARDNESS IN THE LONGITUDINAL DIRECTION FROM THE BEGINNING TO THE REAR OF THE SAMPLES
Keywords:
beech wood, drying, Janka hardnessAbstract
The objective of this study was to determine the hardness of beech wood samples (Fagus sylvatica L.) in the longitudinal direction from the beginning to the rear of the samples versus the method of drying. The warm air-steam mixture drying process and the modified air-drying process were used in the experiment. The warm air-steam mixture drying process, in comparison to the modified air-drying process, caused a reduction of the Janka hardness by about 15.4%. Although the hardness along the length of the sample dried with a mixture of air and steam is leveled, this is not the case for the beginning and the rear of the sample, where drops in hardness are observed.
